![蓝牙未发现任何设备 - Dell XPS 13 (16.04)](https://linux22.com/image/1001547/%E8%93%9D%E7%89%99%E6%9C%AA%E5%8F%91%E7%8E%B0%E4%BB%BB%E4%BD%95%E8%AE%BE%E5%A4%87%20-%20Dell%20XPS%2013%20(16.04).png)
我查看了针对此问题的其他解决方案和线程,但它们都对我不起作用。我正在使用 Dell XPS 13 连接我的新 Jaybird X3 耳机。到目前为止,笔记本电脑无法检测到我的耳机和移动设备。
编辑:所有设备都处于可发现模式。我尝试使用此答案重新安装蓝牙https://askubuntu.com/a/776812/701563但它不起作用。我不知道为什么,但现在 BLueman Assistant 说“未找到适配器”。
我在终端中运行了一些命令,结果如下:

答案1
由于这个答案,我最终能够解决这个问题: https://askubuntu.com/a/920803/701563
步骤1- 列出您的 USB 设备
lsusb
(为我显示了蓝牙)
Bus 002 Device 002: ID 0a5c:216f Broadcom Corp. BCM20702A0 Bluetooth
第2步- 去https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm下载与您的 ID 匹配的已转换驱动程序。对我来说,这是BCM20702A1-0a5c-216f.hcd(点击文件即可下载)
步骤3- 将下载的文件复制到/lib/firmware/brcm
cd ~/Downloads
sudo cp BCM20702A1-0a5c-216f.hcd /lib/firmware/brcm
步骤4- 重启。蓝牙现在应该可以正常工作了。
如果在连接蓝牙音频设备时出现此错误:
Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol Not available
解决方案:https://askubuntu.com/a/801669/701563
sudo apt-get install pulseaudio-module-bluetooth
pactl load-module module-bluetooth-discover
然后,从蓝牙设备中删除该设备并重新配对。
希望这可以帮助您连接蓝牙音频设备。
